triPOS error COM9 Access Denied, Verifone Mx915

I'm seeing "Access to the port 'COM9' is denied" in the verbose.log when starting the TriPosService on Win10, 

although I've gotten triPOS working successfully on Windows7 with the Verifone Mx915 for Authorizations.

 

The port shows as Mx Family POS Terminal (COM9) in Device Manager, "working correctly"
The triPOS API webpage shows correctly from http://localhost:8080/api/help
Version: triPOS 5.14.0.42406

 


From the verbose.log:

2018-04-09 15:37:45,687 [5] triPOS TRACE - SerialClientTransport.cs.TryConnectClient: Is the COM9 serial port open?[False]
2018-04-09 15:37:45,703 [5] triPOS ERROR - SerialClientTransport.cs.TryConnectClient: Error opening serial port

Enabling/Disabling ports in BIOS to match working Win7 machine made no difference.
